Vitamin C's part in collagen synthesis, mapped onto a composite older man's bleeding gums, bruising and slow healing: SC115's Unit 7 micronutrient case brief in its finished state. Searches like "sc 115 unit 7 assignment example", "sc115 unit 7 sample" and "sc115 unit 7 example" land here.
What a finished SC115 Unit 7 micronutrient case brief looks like
The brief opens with the composite case in a short paragraph: age, living situation, a diet described over several months, and the signs a relative noticed, including swollen gums that bleed, pinpoint bruises around hair follicles on the legs, a cut slow to close, and fatigue. The mechanism section follows. Ascorbic acid keeps the iron in prolyl and lysyl hydroxylases in its reduced state, so those enzymes can modify collagen chains that then wind into a stable triple helix. Without it, collagen forms but holds poorly, and each sign in the case is traced to weak collagen in a specific tissue: capillary walls, gum tissue, healing skin. A sources section notes which foods in his pattern supply little, because heat and long storage destroy the vitamin.
How a SC115 Unit 7 example is structured
Four headed sections are typical: case, nutrient function, sign-by-sign analysis, and dietary context, followed by a brief conclusion and references. The function section is the longest and reads as biochemistry, naming the enzymes and the reaction rather than stopping at 'vitamin C helps make collagen'. The sign-by-sign analysis is often set as a table, one row per observed sign, with columns for the tissue involved, the failed step and the textbook source. Dietary context examines the composite pattern for sources and losses, including how prolonged cooking and storage reduce content. The conclusion states that the pattern and signs are consistent with inadequate vitamin C and that confirmation belongs to clinical assessment, which the brief does not attempt. Other contributing nutrients, such as iron, are mentioned where the case suggests them.
Function stated at enzyme level
The brief names the hydroxylation step and the enzymes involved, which is the level SC115 rubrics tend to reward.
Every sign traced to a tissue
Bleeding gums, follicular bruising and slow healing each map to weak collagen in a named tissue, so none is left as a memorized symptom.
Timescale acknowledged
Body stores last weeks to months, and the brief notes the case's long history, which is why signs appear only after sustained low intake.
Losses in the food, not only absence
Canned and long-cooked foods are examined for what heat and storage remove, a chemistry point about an easily oxidized vitamin.
Confirmation left to clinicians
The brief concludes on consistency with the mechanism and stops there, leaving diagnosis and treatment outside the paper.
Where marks go in SC115 Unit 7
The most frequent deduction is a list of symptoms copied from a website with no link to the vitamin's role, which rubrics for this kind of brief tend to penalize. A second is mechanism stated too vaguely to test: 'vitamin C is needed for healthy gums' says what, not why. Chemistry errors cost accuracy points, such as crediting vitamin C with forming the triple helix directly or confusing it with vitamin K where bleeding is concerned. Some briefs overreach and prescribe supplements or doses for the composite person, which falls outside a written case analysis and is marked down. Skipping the dietary analysis, where the pattern and its cooking losses explain the shortfall, leaves the brief incomplete. References to the textbook and one biochemistry or government source are expected in most sections.

Which vitamin or mineral did the Unit 7 case assign? Name it, add whatever case details were supplied, and include the rubric. The brief derives each sign from that nutrient's function, with composite people only, and comes to you inside 24-48h. A first brief is free, whichever nutrient it covers.
SC115 Unit 7 questions, answered
Does the case have to be a deficiency?
Not always. Some prompts assign excess intake instead, such as vitamin A or iron from supplements, and the same logic applies: derive each sign from what the nutrient does at high levels. Follow the prompt's wording, and keep the case composite rather than modeled on someone you know, even with names changed.
How much biochemistry is expected?
Enough to name the reaction or process the nutrient supports and the consequence when it fails. For vitamin C that means hydroxylation of collagen; for B12 it means the reactions tied to DNA synthesis and myelin. Pathway diagrams are rarely required here, but a sentence at enzyme level is usually the difference between partial and full credit.
Can I suggest treatment in the conclusion?
It is safer not to. A case brief in this course explains the mechanism behind a picture; diagnosis, testing and treatment belong to clinicians. Saying the picture is consistent with a shortfall and noting that clinical assessment would be needed is the appropriate endpoint, and graders in most sections expect exactly that restraint.
