than there are carbohydrates.

plz help me I am having exams tomorrow​

Answer 1

Answer:

$\huge{\bf{\blue{\fbox{\underline{\color{red}{Answer}}}}}}$

Explanation:

Ans=1 Like carbohydrates, fats contain carbon, hydrogen, and oxygen, but the proportion of hydrogen to oxygen is not the same as in carbohydrates. Because lipids contain very little oxygen, they can yield large amounts of energy when combined with oxygen.

Ans2 =Proteins have polar C=O. and N-H groups, so they are able to form hydrogen bonds with other molecules and with each other. Carbohydrates have many polar OH groups. A typical carbohydrate is starch, which is consists of many glucose units ( C6H12O6 ) joined together.

Answer 2

chemical structures of carbohydrates and  fats have in common.

• Carbohydrates, Fats, and Oils have in common with each other because all three of them are lipids that store energy
• Differences between carbohydrates and Fats: Chemical composition and structure: Carbohydrates are polymers of monosaccharides, which are polyols (many OH groups) with an aldehyde or ketone functional group.
• Fats are esters of fatty acids and glycerol. Most carbohydrates are hydrophilic, smaller ones are soluble in water.
• Fats also have carboxylic acids with hydrocarbon side chains.  
• They are the simplest form of Lipids. Solubility: Carbohydrates are soluble in water.
• Chemical composition and structure: Carbohydrates are polymers of monosaccharides, which are polyols (many OH groups) with an aldehyde or ketone functional group.
• Fats are esters of fatty acids and glycerol.
• Most carbohydrates are hydrophilic, smaller ones are soluble in water. Fats are hydrophobic.
