NAD+ and NADP+ are coenzyme forms of which B vitamin?Multiple choice question.RiboflavinNiacinThiamin

Break Down the Problem

1. Identify the coenzymes NAD+ and NADP+.
2. Determine which B vitamin they are derived from among the given options: Riboflavin, Niacin, or Thiamin.

Relevant Concepts

• NAD+ (Nicotinamide adenine dinucleotide) and NADP+ (Nicotinamide adenine dinucleotide phosphate) are both coenzymes involved in redox reactions in the body.
• These coenzymes are forms of Nicotinamide, which is derived from the B vitamin Niacin (Vitamin B3).

Analysis and Detail

• Riboflavin (Vitamin B2) is associated with FMN and FAD.
• Thiamin (Vitamin B1) is related to the coenzyme thiamine pyrophosphate.
• Niacin (Vitamin B3) is specifically linked to NAD+ and NADP+.

Verify and Summarize

Since NAD+ and NADP+ are directly derived from Niacin (Vitamin B3), the appropriate choice from the provided options is clear.

Final Answer

NAD+ and NADP+ are coenzyme forms of Niacin.
