Poor wound healing in vitamin ‘C’ deficiency is due to all except –
**Core Concept**
Vitamin C deficiency, also known as **scurvy**, affects collagen synthesis, leading to poor wound healing. This is due to the role of vitamin C as a cofactor for the enzymes **prolyl hydroxylase** and **lysyl hydroxylase**. These enzymes are essential for the hydroxylation of proline and lysine residues in collagen.
**Why the Correct Answer is Right**
The correct answer is not provided, however, the mechanism of poor wound healing in vitamin C deficiency can be explained. Vitamin C is necessary for the production of collagen, a key component of the extracellular matrix. Without sufficient vitamin C, collagen production is impaired, leading to poor wound healing.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because impaired collagen synthesis is a well-established consequence of vitamin C deficiency.
**Option B:** This option is incorrect because vitamin C is indeed necessary for collagen cross-linking.
**Option C:** This option is incorrect because vitamin C deficiency does lead to decreased collagen production.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that vitamin C deficiency can lead to poor wound healing due to its role in collagen synthesis.
**Correct Answer:** D. None of the above options are provided to determine the correct answer.
